SKATE SHABPENER:

Application filed October 20, 1928, Seria1 no; 313,867. Renewed. January8, 1931. f

This invention relates to sharpeners and its general object is toprovide a hand sharpener for skates that is rimarily adapted to finishor complete the s arpening ofv the ice 5 engaging surface of the runnerof skates in a manner whereby a perfect skating surface is assured.

Another object of the invention is-to provide a hand sharpener forskates that will sharpen the blade of a skate after the same has worndown adjacent to the blade, brace or support. 8

A further object of the invention is to provide a skate sharpener thathas stone for its abrasive element, with guards for the stone and theguards also act as guides during the sharpening operation. A stillfurther obj ect of the inventionis to provide a skate sharpener that isextremely 2 simple in construction, inexpensive tomanufacture, easy touse and efiicient in operation and service. This invention also consistsin certain other features of construction and in the combination andarrangement of the several parts, to be hereinafter fully described,illustrated in the accompanying drawings and specifically pointed out inthe appended claims. 1

. Indescribing my invention in detail, ref

erence will be had to the accompanying drawings wherein like charactersdenote like Referring to the drawings in detail, the

letter A indicates an ice skate of a well known construction and B theblade thereof. While I have illustrated my sharpener in use upon a skateof the type vas shown, it will be obvious that it can be used on iceskates of all ty es. The blade B has cits ice engaging sur ace 5 formedwith a longitudinally disposed groove as will be noted uponinspection'of-Figures 2 to 5 inclusive.- a I The sharpener includes astone 1 that is 63 substantially wedge shape in cross section and has aroundedsmall edge 2 that is adapted for fitting engagement 1n the'grooveY of the blade B.. V r

The stone is formed with spaced parallel to openings arranged adjacent,the top or enlarged edge thereof, and these openings may be reinforcedby sleeves if it is found desirable, but in an event pins 3 are passedthrough-the openings and are formed-with I headso'n their opposite endsfor the purpose of securing plates't to the pins, that not only provideahandle as well a'sa guard for the stone,but -theplates extend for thegreatest portion ofthe'ir lower edges, belowthe small or'lower edge ofthe stone as suggested in Figure 1 to provide guides. The plates 4 arearranged upon opposite sides of the stone and'are loosely'mounted on thepins so that they may be moved if desired in a ,plane'as suggested inFigure 3.

- The forward corners of theplates 4 are beveled .or cut-away, and thelower cut-away portions which fordistincti'on are indicated by thereference numeral 5 provide for the projection'of tlie'forward loweredge of the stone beyond the cut-away portions soith'at when a-blade hasbecome worn down to adjacent' the brace or support thereof, theprojecting portion of-the stone will be able to engage the ice-engagingsurface of the blade as will be apparent. I r

1 One of the ends of'th'e stone terminate approximately in'alignme'ntwith one of the endsof the plates, and'these mentionedends 790constitute'the forward or. front end of the device, but it will be notedthat the stone is considerably longer than the plates and extends beyondthe rear ends thereof for a purpose which will be presently apparent.".95

From the above description and disclosure of the drawings, it will beobvious that I have provided a sharpener that is primarily designed forfinishing and completing the ice engaging surface of the blade of askate, and due to providing a stone with a rounded lower edge as shown,with the rounded lower edge being of a size to be received in thelongltudinally disposed groove of the blade, the sharpener will removeall rough surfaces from the groove as well as from the outer edgesthereof when the shar ener is used in the manner as illustrated in Fiures 1, 2 and 3. v

11 order to retain the small edge of the stone rounded in cross sectionas shown, the blade of the skate is reciprocated from its full lineposition as shown in Figure 3 to its dotted line position, and thissharpening action is made possible by the novel means of securing theplates to the stone.

v The rearward projecting end of the stone is primarily used forremoving burrs, roughened places and the like upon theopposite sides ofthe blade adjacent its ice engaging surface, and when this function isaccomplished, the sharpener is disposed with respect, to the skate bladein the manner as shown in Figures 4 and 5. 7

It is thought from the foregoing description that the advantages andnovel features of m invention will be readily apparent.

I esire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall Within the scope of the appended claims.

What I claim is: i 1. A sharpener of the character described comprisinga stone, plates loosely secured upon opposite sides of said stone toallow swinging movement thereof and terminating below one of the ed esof the stone, said plates having one 0%their lower corners cut-away fordisposing a corner of the stone below the cut-away ortions. V

2. A sharpener of the character described comprising a stonesubstantially wedge shape in cross section, plates loosely secured tosaid stone to allow swinging movement thereof and disposed upon oppositesides of the stone and below the same, said plates having the greatestportion of the lower edges disposed below the small edge of said stone,the remaining ortion of the lower edges being outawa or disposing acorner of the stone below t e plates, and said stone being of a lengthfor disposin a portion thereof beyond one of the ends 0- said plates.

In testimony whereof I aflix my signature;
